Are there any keyboard shortcuts for RadioButton and Checkbox?

I have a lot of data-entryists using my ASP.NET application and we have all been wondering if there are any keyboard keys or shortcuts that you can press to trigger:

• Check a RadioButton
• Uncheck a RadioButton
• Check a Checkbox
• Uncheck a Checkbox

I know that you can write Javascript and do开发者_开发百科 it yourself, but do any keyboard keys/shortcuts already exist without using the mouse?

Spacebar is the standard button for those, with arrow keys to move between radio buttons.
